We've got an exclusive preview from the upcoming reissue of the Who's early '70s update of Tommy with the London Symphony Orchestra and Chambre Choir. And it features an intersection of two of rock's greatest bands.

The Who's Roger Daltrey, John Entwistle and Pete Townshend appeared on the original orchestral remake of the album, which was produced by Lou Reizner in 1972 but has been out of print for three decades.

The LP's special guests included Beatles legend Ringo Starr, the featured vocalist on the exclusive preview of "Tommy's Holiday Camp." Elsewhere, this Grammy award-winning project includes guest turns by Rod Stewart (his take on "Pinball Wizard" remains a highlight), Steve Winwood, Richie Havens and others.

You can listen to "Tommy's Holiday Camp" below.

"I always saw the Who's [original 1969] version of Tommy as more of a sketch, and felt there was more that could be done with it," Pete Townshend says in a press release for the reissue. "The London Symphony project, I think, paved the way for more to come."

This orchestral edition of Tommy – conducted by David Measham and arranged by Wil Malone – will be available Sept. 11 as a CD, digital download and gray vinyl. The original libretto, with a 20-page color illustration outlining the characters and lyrics, will also be included in the vinyl edition.
